This was a top-of-the-line ultrabook in 2002, I got mine 'cause someone was throwing it away in 2019. It has 512 megs of RAM and runs Windows XP nicely! Mine's setup to replace my XP Virtualbox image I use for sword_of_moonlight and Klik & Play. Would've liked to run Windows 3.x on there, but apparently it's not MS-DOS-friendly, drivers-wise.
